           Summary: Segmentation fault with anon class in anon class and
                    non-constant variable init
           Product: D
           Version: 1.025
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: benoit@tionex.de


This is not valid D code, but obviously DMD should not segfault on this:


interface I {
}
interface K {
    void func();
}

class C{
    this(){
        I i = new class() I {
            K k = new class() K {
                void func(){
                    this.outer.outer;
                }
            };
        };
    }
    int i;
}

void main(){
}

------- Comment #1 from clugdbug@yahoo.com.au  2009-04-18 03:38 -------
Don't know what the error message should be, but this patch at least fixes the
segfault for DMD2.028.
Note that in this bug, there are also error messages with no line number.

Error: variable this forward referenced
Error: variable this forward referenced
fog.d(12): Error: No parent
-----

The line number is known in mtype.c line 6070, but isn't known in the variable declaration itself.

---
 v = s->isVarDeclaration();
    if (v && !v->isDataseg())
    {   Expression *ei = v->getConstInitializer();
